ELEVATING-TRUCK.

Specification of Letters Patent.

Patented Dec. 28, 1915.

To all whom it may concern Be it ltnown that I, Mioimnn licence, a citizen of the United States of .c-imerica. and resident of Uhicopee, in the county of Hampden and State of Massachusetts, have invented. certain new and useful Improve.

ments in Elevating-Trucks, of which the following is a full, clear, and exact descrip tion.

This intention. for improvements in elevat-ing and eighing trucks, relates to improvements whereby when the trucl: has received its lead. weighed or to re weighed by the scale system or mechanism with which the truck is equipped. and the elevatahle portion of the truck is raised, as for the purpose of lifting the load, and therewith the skid or table-like support on which the load had primarily been sustained, for transportation, the load will be sustained by supports appurtenant and supplemental to the elevatahle portion of the truck above the level of the platform of the scale, so that in the travel of the truck the load will be free and independent of the scale, and have no tendency to cause joggling of the scale and injury thereto.

The invention is described in conjunction with the accompanying drawings and is set forth in the claims.

In the drawings: Figures 1. 2 and 3 are side elevations of the improved truck, showing, firstly the truck lowered, secondly the truck raised but having the side portions thereof lower than th. scale platform. and thirdly. the truck raised and having the supplemental supports by which the load is carried, raised above the platform of the scale. Figs. 1 2 and 3 are diagrammatic views showing the cross sectional. aspects of the portions of the truck when in the positions corresponding to Figs. 1, 2 and 3 respectively. Fig. at is a plan view of the truck, the platform of the weighing scale being understord as removed. Fig. 5 is a longitudinal vertical section on line5 5,Fig. 4.. Figs. 6 and 7 are partial sectional elevations as seen beyond the plane indicated by line ('l-'T Fig. i, for showing the different positions of the rockshaft and its operating lever hereinafter referred to.

The elevating truck shown in the present drawings is of a construction substantially corresponding to that shown and described in an application for Letters Patent of the Uiited States filed by me December 14 191%, Serial No. 877,062.

In the drawings, A represents the lower or main trucl: frame provided with rear and front of rollers a a and E) b and raving thereon the elevating frame comprising the opposite longitudinally ranging side bars B.

Inasmuch as the nature and use of an elevating truck are well known, it is not deemed defrahle or necess ry to herein describe the detail construction of the present elevating truck and especially inasmuch as this invention is not limited to any particular construction of trncir. It will be mentioned, however, that the front rollers 7) b of the track are mounted on an axle sustained in a head or frame which may both swivel on a vertical axis for steering and oscillate on. a horizontal axis,see Figs. 2 and 3 as compared with Fig. 1, for effecting, through interlocking mechanism between the oscillatory head and the elevating frame, the r. ising and lowering of the latter. The opposite sidebars B B of the elevating frame are transversely united at their forward portions by an upright or standard C,c 0 representing attaching angle members therefor.

The elevating frame in which the opvosite parallel longitudinal side bars B B are comprised carries a weighing scale, the lever system of which is in a general way represented by (Z in the drawings, such lever system having a frame dimposed thereon and on which the platform (Z of the scale rests. The weight determining portion of the scale is link connected to the lever system (Z and the location thereof is indicated by (1* forward of the upright C. The scale platform (Z as especially shown in. all of the Figs. 1 2, 3 is slightly above the upper edges of the side bars 13 B of the elevating frame.

D D represent a pair of side bars arranged alongside of and adjacent the side bars B B of the elevating. scale-carrying frame; and the adjacent side bars B and D at each side of the truck have, at diilerent portions in the length thereof, the one a pair of transverse studs 7 and the other slots 9 inclined to the length of the bar in and through which the studs engage.

As hero shown, the studs 7 are provided as outward transverse projections of the elevating frame bars B, and the slots (r are formed in the bars D. lhe inclin slots have portions (her represented as the fomvard end portion of each),a short on tension g which is along the horizontal longitl'ldinal line of the bar.

F represents a roclzshaft transversely mounted in a bearing slot 7t therefor in brackets i extending rearwardly from the lower portion of the upright v. This rockshaft has at the opposite ends thereof rigidly fixed lever arms which are pivoted at their outer ends to the bars D D. The rockshaft has a forwardly extending lever arm 73 rigidlv connected thereto and by means of which the rockshaft is oscillated.

When the side bars D D are in their lowered position, as shown in Fig. l, with the right hand and higher portions of the slots 9 next to the studs 7'" and the lever 0 depressed to rock the siaft and sw' vill by the impingement of the slot against the studs cause the elevation of the bars from the position relatively to the truck frame bars D shown in Figs. 1 1 to the positions shown in F 3, and Si reference in this connection being also had to Figs. 6 and 7 and also to the relative positions of the upper edges of the side bars D D and the platform d of the scale. The outside bars D D bein' to the rightward and elevated have s sitions that the left hand, substantii zontal or longitudinal end portions 9 of the slots are next to the s uds, and by rea son of the stated formation of such. end extensions the bars are locked in their ele vated position, and the tendency of the weight or load which may be s stain-st by such bars will be without efiect to cause relative movement between the slot walls and studs, or permit of any movement of the actuating); rockshaft excepting as such is purposely performed.

By dotted lines in Figs. 1, 2, and 3, the skid y for the load is shown. In 1 the skid is represented in relation to the truck in its lowered condition, the feet of the resting on the floor while its horizontal load supporting portion is above and free from the truck and its platform. In Fin; the

truck is represented as elevated, the side bars D being in the lower relation to the side bars B of the elevating fram e scale e th platform is shown above the elevatinr' frame, and the skid with its load is r sented as lifted free from the floor and restins 011 the scale platform and thus capable of being weighed. In Fig. the side bars D of the elevating portion of the truck are represented as thrown upwardly to a level A T k: L them the latter position.

above that of the scale platform so that the loadi carried by such bars and the scale platform is relieved of the weight.

(has of several manners of use the trucl: she l and 1, to run tl e truck under the skid supported load, then to can e the elevation to take the load aboard to platform, as indicated by Fig. then weigh the load and note the it thereof; and then to lot the elevatportion of the truck down to the posiof i to next elevate the outside above the edges of the bars l3 l3, Le; through the powerful moans actu- J n the medium of the lever-like l ale and front connected, effect the raising of portion of the truck, and as the upwardly positioned side to take the weight so that in. the cation there will be no cause for the platform and other parts with consequent liability of intlOll in the novel part of znav be made without t einvention.

i x3e from this I claim A truck cmnprising a main frame, and .me elevatable and depressible relatively thereto, a weighing scale carried by the ele- Irame, and comprising a platform an such frame, members carried ble scale carrying frame, movposition below to a position cale platform, and position-shifta .s for said members. truck comprising a main frame, and me e ,evatable and depressible relatively tl'iereto, a weighing scale carried by the ele frame, and comprising a platform lier than such frame, members carried by the elevatable scale carrying frame, movable from a position below to a position the scale platform, and means for ff the said members from their lowto raised position and for lochin 1. truck comprising a main frame, and
